I'm glad to see that someone else is working on SF! I always thought it was a wonderful mod, just in need of some tweaks. I worked somewhat diligently at patching it for a while, but real life eventually got in the way. Plus, I'm not really all that versed in ACS / general Doom modding stuff, so none of the changes were ever technically very impressive under the hood.
I'll have to make some time to check out the current state of things!
